Tail Virus Gym Sharks

It turns out the rumors Essa heard about designer Tail Virus strains being sold on the dark web were true. Even better, she found an experimental strain that would take her physique to the max while helping her embody her love of sharks.

With the syringe she ordered in her gym bag and her diminutive boyfriend Taylor in tow, Essa's headed to the gym. Nothing in the listing for this Tail Virus strain seemed that over-the-top, so she's assuming it'll just enhance her performance while giving her some shark traits.

Essa's assumptions are off base, however, because she didn't think too hard about the experimental nature of this strain. 

In addition to her outgrowing her gym clothes, she's in for a big, throbbing surprise. A throbbing surprise that's going to end up inside Taylor's brand new Tail-Virus-provided pussy by the time this transformative trip to the gym is over.

Tail Virus Gym Sharks

By Zmeydros (Mae Singlais)
(Edited by: Tiliquain and WolfLeah)

It was a typical late Wednesday evening at Dumbbells and Deadlifts. The gym was a cool seventy degrees and only half the weight machines were being used by regular weekday lifters as they went through their routines. The stark white light from the overhead LED fixtures was bluer than Essa preferred, but she figured they were meant to keep people alert by replicating daylight. The problem was that the yellow in the gym's black, gray, and yellow color scheme was being tinted to an unflattering, bright yellow-green. And that yellow was everywhere, even on the lockers.

Essa's biceps bulged less than she hoped as she set her gym bag on the blonde wooden bench in front of the yellow lockers. Her chin-length black hair hung in her face, breaking up her view of Taylor's small-but-fit form as he set his gym bag down next to hers. Standing up and pulling her hair out of her face, Essa sighed. Her body just did not fit her, like at all, and going to the gym was starting to remind her of that without giving her any hope.

As Taylor changed out of his khakis and light blue dress shirt, Essa unzipped the side pocket on her black duffel bag and pulled out a one inch by four inch long box. It had what looked like a prescription written on it. "Buff Shark Serum" and "Avoid a $1000 Fine: Send All Materials Back to Sarducci Labs After Use" was in large letters  while "Warning: Experimental Strain. Contains Shark, Equine, and Dragon Mosaic DNA" were written in much smaller letters. She set it aside on the bench before pulling off her green-gray long-sleeve blouse and tossing it in the locker next to Taylor's. Then she took off her padded bra which had been putting in a lot of work to show off her modest bust.

Taylor's eyes immediately darted to Essa's tits, which got her to smile and turn toward him.

"Can't get enough of their perfect shape." Taylor grinned, his five-foot-four frame buzzing with energy.

"That's the only thing they've got going for them." Essa unbuttoned her jeans and pulled them off.

"Don't say that, they're gorgeous, just like the rest of you." Taylor's little cock was starting to make a tent in his red-and-white striped boxers.

"I wish I could just take the way you feel about me and make it the way I feel about myself. But that's just not how shit works." She shook her head. "I've been at this for three years. Even with the guidance of a personal trainer and sucking down enough whey protein to cause a state-wide shortage, I can only lift half of your bodyweight. I'm sick of domming you while an inch shorter than your adorable ass. And I deserve far more curves than I have."

"You absolutely deserve to be happy with your body and I know things are going slower than you'd like. But when you started, you could only bench twenty-five pounds. Now you're almost at sixty. That's some massive improvement, hon. You'll get there, I know you will." He hugged her from the side.

"Even if I get to the peak of what an average woman can do after years of training, it'll do nothing about my height or my flat, string-bean-like body." She gave him a quick hug back and then picked up the box she'd set down. "That's why I'm so happy this showed up today."

"So that's what was in the padded envelope you were being all secretive about." Taylor started reading the label. "Wait. How did you get your hands on a Tail Virus strain? Why did you--?"

"I just told you why, dear. And to answer your other question: they're being sold by special, not-quite-legal labs if you know where to look." Essa opened the box and pulled out a small syringe that was shrink wrapped to a piece of magenta paper.

"Are you sure about this? You're going to end up a--shark?--mosaic." His brow furrowed.

"A big buff shark mosaic who can pick you up and have her way with you." Essa grinned, peeling the plastic off of the paper to get at the syringe. Inside the syringe was a milliliter of clear liquid.

"That does sound hot." He paused, resting his jaw on the space between his right index finger and thumb. "It says it's experimental, though."

"None of the possible side effects were things we wouldn't like. Sometimes the dragon or horse comes out more than the shark, little stuff, like that." After pulling a small band-aid and alcohol wipe out of the box, she unfolded the directions for administering the shot. "I mainly just want the physique."

"It's your body and it sounds like all the options are pretty sexy." He tilted his head as he thought about it more. "You're going to be infectious for a while after, so I guess we'll have to be careful." 

"Yeah, unless you want to get infected and be part shark too." She looked him right in the eye. "That said, I doubt this strain would give you what you want. How, about, if this works, I'll get you a strain that'll give you a pussy I can fuck?"

"NGH! Hey! Not where others can hear." He squirmed.

"No one's in here, dear." She leaned in and grabbed the four-inch tent in his boxers. "I know how much you want a nice, juicy pussy that gets all wet when I look down at you and call you a good girl."

"Fuck! Okay, okay. Just take the shot and stop teasing me." He looked down at the pre-soaked spot on his boxers and her fist, which was still wrapped around his member.

"Glad you're on board because I've never wanted to do anything more in my life." She let go of his dick and put the directions back in the box.

Using her hands to measure out two palm lengths from her left knee, she found her injection site. Then she used the alcohol wipe and popped the protective cap off the syringe. It wasn't that long of a needle and it was pretty thin, so when she jabbed it into the top of her leg, she barely felt it. Then she depressed the plunger and pulled the needle out.

"Oh shit! Why aren't you doing this at home?" Taylor was staring at the injection site. "Will your clothes even fit afterwards?"

"Hon, it's not like it's going to change me that fast." She chuckled.

"I mean, Tail Virus stuff can go really fast, though." He got up and pulled out his gray-blue gym shorts.

"Well, if it does, I guess I'll end up putting on a show."

"Do you never get embarrassed?" He put his shorts on and then a gray-blue gym shirt with light blue seams on it.

"Only embarrassing thing about me is this short, scrawny body of mine. If that gets better, I'll WANT people to look." She put on a pair of light gray-green gym shorts with green trim and a matching sports-bra-like top before she slipped on her orange workout shoes.

"The way you use your body, I would never call you scrawny." He put on his blue workout shoes.

"You're so cute." She grabbed his ass and pulled him against her front before kissing him ferociously.

He moaned, swaying in her embrace while his prick poked between her thighs. After she ended the kiss, she held onto him to make sure he'd stay upright.

"I'm gonna need a moment to calm down. You go ahead and I'll join you." He blushed.

"Sounds good." She ran her right index finger over his prick, making him gasp. Then she turned and trotted out through the swinging locker room door into the gym.

The weight machines, walls, and doors had yellow accents, but the weights and bars themselves were pretty standard. The room was much longer than it was wide, but it was still wide enough to have weight machines and weight benches on both sides. The flooring of the entire gym had some give to it and was made out a rubber surface that had been repurposed from car tires. The rubber smell was ever-present, but not overwhelming. The smell of old sweat was just like every other gym Essa had been in. 

The locker room opened up into a twenty by twenty foot area where people did warm ups, yoga, and other things that didn't require weight benches or machines. Along the walls of this area were yoga balls, medicine balls, and dumbells.

Of the eleven other gymgoers, four of them were mosaics. One was a very fit tigress with half of her shoulder-length black hair dyed red and a sizable bulge. She was using one of the far weight benches. Another was a voluptuous, feminine deer with a bulge that rivaled the tigress's. The deer was doing leg lifts. The other two were at a bench press. A small masculine otter was spotting for a butch femme bear. Essa often didn't pay a lot of attention to humans, but a couple of them stood out. 

Cash, a tall, muscular enby with purple-streaked hair was currently doing intimidatingly huge deadlifts, while a stocky, thirty-something guy with copper-colored hair was doing pull-ups on a bar near Essa.

Essa walked to her right far enough that she wasn't blocking the door and then started doing jumping jacks. At first, it felt like any other day at the gym. Once she'd been doing them for a bit, however, the place she'd injected started to ache. When she looked down, she saw sea blue scales spreading out from the injection site.

She grinned as she felt the ache spread up her leg, across her abdomen, and then settle on her breasts. Her tits pulsed as she jumped over and over, flailing more as they expanded noticeably. The sensation only lasted for a couple minutes before her pussy started to ache more than any other part of her. It pressed harder and harder against her panties and gym shorts, getting wetter and wetter. Soon, it felt downright slippery between her legs.

As the ache encompassed her entire body, her gym clothing, and even her shoes, started feeling tight. Things in the room looked a little shorter, like she had to look down more at them. Were her quads always that thick? Her legs this long? She looked at her biceps and swore they were thicker too. A giddy thrill was now running through her. This was fantastic!

The scales filling in on her belly and chest were a beautiful shade of bluish-white. Satisfied with her warm up, she took the time to marvel at them. They were smoother rubbing downwards than they were rubbing upwards. The difference wasn't as stark as it was with an actual shark, though. It was pleasant, and not all that rough, no matter which direction she traced her fingers over them.

Cash looked over at her and raised an eyebrow. Their face was long, but had a soft chin and cute nose.

While Essa smiled at them, Taylor walked into the gym.

"Hey, Taylor! Look!" Essa pointed at the scales on her legs and exposed belly.

"Wait, you're changing already?" He took a couple steps toward her, bending forward to get a better look. "That's a beautiful color."

"Yeah! Isn't it?" She pushed out her chest. "I think these got bigger too." Her tits pressed outwards, gaining half a cup size as her legs ached, adding an inch of height.

"A-all of you looks bigger." His mouth hung open as he watched her body change right before his eyes. He was now forced to tilt his head back a bit to see her face.

"I'm gonna continue my routine. You should warm up," she said, walking over to the nearest weight rack.

He started jumping jacks, but couldn't take his eyes off of her. She grabbed a long bar and put a twenty-five pound weight on one end of it. Sticking the other end of the bar in the corner between the wall and the floor, she lowered the end with the weight to the floor. Then she crouched down, grabbed that end with both hands, and lifted while the far end of the bar stayed put.

Each time she did a rep of this exercise, it got easier and her gym clothes got tighter. By the fifth rep, she had to lift the bar noticeably higher to reach the end of her range of motion. Her tits were twice as big as they had been, her nipples and areolas were wider too. The sports-bra-like top she was wearing was starting to tear. 

The changes felt good, too good. Her clit was aching furiously and her cooch sent sparks of pleasure through her each time she had to squat, stretching her gym shorts firmly against her aching fem parts. A moan escaped her lips during the next couple reps. 

With her cheeks burning from a blush, she took a brief rest. Her breaths came out in hot puffs while pain built in her jaws. Then her nose felt funny, like it was getting pushed on. She crossed her eyes, trying to look at it, and watched its fuzzy outline shrink into her face. Her gums felt like they were getting pinched, but as her face pressed outwards, the pain lessened, until the extra teeth coming in hurt enough that she started her second set of reps to distract herself.

Lifting got easier as the shape of her muscular ass became extremely well defined in her gym shorts. She chuckled to herself: for the first time in her life, she felt powerful. Her ears were warm, like they were under a heat lamp, as they got pointier and stretched out into a shape that was somewhat canine, but longer and thinner.

As her ears continued to grow, there was an odd, clenching feeling deep inside her abdomen. Unbeknownst to her, her ovaries were enlarging and then dividing into her new testes. This sensation got more intense while her clit pulsed so strongly that she struggled to lift evenly. Each time she stood up from a crouch, her clit pressed harder against her panties and labia. When she looked down to see the little hill it was making in her gym shorts, her cheeks flushed and she let out a huff. She'd never thought about having a huge clit, but fuck, it was hot. 

Turning toward the wall, she reached down between her legs and touched it with her right index finger. "NGH! Fuuhhhck!" It was so rigid, so sensitive, and amazing. Her cheeks burned at the thought of it getting even bigger.

After she finished her final set of reps and put the bar away, the changes to her jaws and face worked their way toward completion. She felt over her shark snout, loving the angular shape of it and the sharp teeth that were filling in the gaps toward the front. Being shaped more like a predator, with front teeth she could easily use to defend herself, made her feel more dominant than ever. Plus, she had obvious muscles now and was at least five inches taller than she'd been before all this started.

Strutting over to a mirror near the weights, she gasped at what she saw. Her tits were double D's or larger, her hips and ass had an actual curve to them, and her muscles were far more defined. The bluish-white of her belly and the sea blue of her other scales looked gorgeous, even in the awful lighting of the gym. 

As she posed, flexing her biceps, her pussy clenched and something moved inside her. It was a half inch of movement down the front of her vaginal canal, but it felt like a deep penetration. Her breath caught in her throat while her clit gained a whole inch. The change took a good ten seconds, and by the time it stopped, she was just a hair's breadth away from cumming.

In the mirror, she saw Taylor hard at work with leg presses. Smirking to herself, she strutted over to him.

Cash's eyes darted to the two-inch rise in Essa's gym shorts and then across her body. Their eyes were wide and their cheeks flushed as they fully took in what was going on. The pudgy redhead near Cash had even redder cheeks and his eyes kept dropping to Essa's groin only for him to bring them up to her face or breasts. The tigress with a bulge glanced in Essa's direction and then looked her up and down before grinning knowingly.

Seeing the attention she was getting, Essa's strutting got more sensual. When Taylor caught sight of her, he stopped dead.

"Hey," she said confidently with her lower, more sultry voice. It felt weird to form words with her shark snout, but she was hiding that fact well.

"E-Essa?!" Taylor's eyes moved over her snout, powerful shoulders, biceps, bigger tits, and then his eyes widened at the tent in her gym shorts. "Wow, you-you're--"

"Blazing hot, right?" Essa tilted her hips, making the tent more prominent.

Taylor lowered the weight he'd been lifting with his legs and then nodded. His blush was making it part way down his neck.

"I want you to spot me while I do hip thrusts." She grinned.

"You don't normally need a spotter for that." He gulped, his eyes still wide and taking in her new features.

"Is that a no?" She grinned wider, showing off her shark teeth.

"No, I mean yes, I mean I'll do it ma'am." Taylor's erection was clear in his gym shorts.

"Good girl." Essa led him over to a weight bench and got a long bar. Then she put forty pound weights on either end, finding them oddly easy to handle.

She gave the bar to Taylor and then sat at the side of a weight bench, her feet planted on the floor, before motioning for him to hand the bar to her. She put it across her hips, right where the bend of her legs started. Then she shoved her hips upwards, pushing with her core and her legs. She let it down, going back to her seated position. As she made her way down, her toes pressed against the end of her shoes. Her toenails tapered into claws just before her feet expanded by two shoe sizes, tearing open her shoes. She gained two more shoe sizes, splitting her shoes completely open just above the heel. Chuckling as Taylor stared in awe, she did another rep. A tingle built in her tailbone and her muscles burned, but not from the effort.

"Not nearly enough weight. I'm hardly noticing that." She laughed. "This is incredible! Add another forty to each side." That knot in her abdomen moved further down the front of her pussy while her clit pulsed larger. "NGH!"

"You doing okay?" Taylor asked as he put the first extra weight on the bar.

"Never been better, honestly. It's just that I'm changing so fast that I'm getting some pretty intense sensations." She watched Taylor put the second weight on. Her tailbone felt like it was getting squeezed and then she noticed that it was pressing against her panties.

"Do you think you're getting a cock?" He asked quietly.

"Maybe?" She watched her clit pulse for a moment and then got a rush of excitement. She'd never seriously thought about having one of her own before. A big, toothy grin formed on her snout. "Honestly, I hope so."

"Y-you want one?" He bit his lip, his cheeks flushing.

"I'd get to feel what it's like to be inside you. Plus, I've always wondered what it felt like to shoot a load." She thrust her hips upwards, finding it too easy still. Her body got an inch taller while her muscles bulked up. Her clit was now at least six inches long and had a flat head that looked kinda familiar.

"Oh, wow." He pressed his legs together, his small erection making a cute tent in his shorts.

"Hot, huh?" She grunted as she got the urge to push. A wave of pleasure washed over her as she did so and she felt whatever was moving inside her get pretty close to her groin. She spoke quietly. "You know I'd make you drink down every drop."

"NGH! Haah!" He stifled a moan, looking at her as his prick reached full hardness in his pants.

"You're cute. Let's put another eighty pounds on each side. I'm barely feeling this."  She motioned toward the weights against the wall. The bud of her tail pushed out far enough to deflect the waistband of her gym shorts and one of the stitches in the seam that ran up the middle popped.

"Are you sure? That's a lot. No way I could spot that." He was squirming, stepping from one foot to the other. Something about the way he was placing his hands in front of himself, and the way he had his shoulders folded forward, was so girly. Catching a glimpse of his feminine side always made her want him more.

"I'm sure. I promise I won't strain myself." 

"Okay, if you're sure." Turning toward the weights, he grabbed the first plate with both hands and carried it to the left side of the bar.

As she watched him get the weight, her eyes fixed on his shapely behind. Even if she wasn't getting a cock, her clit was plenty long enough to plow him when they got home. She got the urge to push again and did so while he finished getting the extra weight on both sides of the bar. The pleasure-giving knot that was moving down the front of her pussy stopped just behind her clit. She could feel some flesh that had bunched up below her clit and her eyes widened as she realized what might've been moving inside her all this time.

"I'll be careful, I promise." She gave his ass a reassuring grope.

"Ngh!" He squirmed. "Okay. It looks like you might have the bulk to pull it off, but I'll be right here just in case."

"Thanks!" She grabbed the bar to make sure it stayed straight across her hips.

Then she grunted as she pushed upwards. She could feel her massive quads and glutes contracting. Her core was feeling the burn too and every inch she lifted the three hundred and twenty pounds of weight off the ground was a huge effort. At three inches off the ground, all that pushing popped her balls into her brand new sac with a thud.

"HAAAH! FUCK!" She cried out as she kept going, a female orgasm crashing through her. It felt like her whole body had been dropped into a warm, frothy sea. Her clit was now clearly a cock and a new clit gave her a jolt of pleasure as it plumped up just behind her sac. Now she had two orgasms reverberating inside her at the same time. Her brand new balls ballooned in size as her muscles and body got a surge of growth. She spurted so much precum so hard that it shot up through her gym shorts, splattering on Taylor's right arm.

"Umm, Essa? Maybe you should stop." He reached out for the weight even though he didn't have a good angle to grab it.

"No, it feels incredible." Inches were added to her tail in seconds as she got past the halfway point. Seams and elastic threads in her gym shorts were tearing, making a racket. Her prick gained a medial ring and an obvious flare, making it fully equine.

Cash and the redhead were staring in her direction. The hung tigress had an equine erection running down her gym shorts. The deer was trying not to look, but couldn't keep her eyes away. Her tight blue leggings were making it quite obvious that the tip of her conical cervine erection was clearing her sheath.

"RRRRAAHHHH!" As Essa got eighty percent through her hip thrust, her equine cock suddenly grew from seven inches long to over twelve and her tail burst out of the back of her gym shorts and panties. Due to all the elastic in them, her precum-and-girl-juice-soaked shorts slingshotted themselves right into Taylor's chin.

"ESSA?!" He grabbed the shorts and tossed them to the ground, looking at her dick like he needed to dive on top of it to hide it from the rest of the gym.

"Feelssss ssssOOOH GOOD!" Her tits expanded, tearing the seams on her sports-bra-like top until it split open and her humongous  tits fell out. As she reached seven feet in height, her build became that of a female fitness goddess. Her tail rocketed longer, vertebrae popping into existence one by one. At the top of her thrust, her cock lurched and a rope of pre splattered across her snout. She licked it up, enjoying the salty, melony flavor for the first time.

Taylor's face and neck were pink with a blush that was making it all the way up to his ears.

She let the weight down as her pussy clenched and prick started lurching again. Her balls were about half the size of her fists, but they were quickly growing. There was a pressure at the base of her dick that got worse as it gradually grew three more inches. The way her cock flesh was stretching and changing felt like it was being stroked and fondled. Her whole front flushed as she frantically lifted the bar off of her loins and got out from under it. A resounding clang echoed off the walls as it slammed into the rubber floor. She felt like the pressure inside her was going to burst forth any second.

"Ngh! I still have my pussy, so it's gotta be the herm strain."  She could feel something thicker than her pre moving up her shaft. Her fingertips and long ears tingled. Unable to resist, she started stroking her shaft with her right hand. Pleasure jolted through her as she thrust her hips into her grasp.  "HAAAH! I'm gonna blow! Come and get it!"

"It's so big..." He knelt down next to her, astonishment causing his jaw to drop open. "And wait, you still have your pussy?"

"Yeah! Holy FUUU-RRRAAAHHH!" She growled as the flare and medial ring on her dick expanded and pearly white cream shot out from her equine cum hole. It hit her tits and then her chin and then she grabbed his head with her left hand and put his mouth on the end. "Drink it, SLUT!"

He guzzled the cum that flooded into his mouth like he'd been waiting all evening to please her. After the last spurt cleared her shaft, his eyes were glassy for a moment, staring at her loins, but then they widened. Pulling off her dick, he panted and licked excess cum off his lips.

"You okay, hon?" A little bit of guilt welled up in her as she realized what had just happened.

"Never imagined this was how I'd get the Tail Virus. I kinda lost all my self control when I found out it was the herm strain." He bit his lip.

"Sorry, dear." She sighed. "I lost control too. I let my brand new cock do the thinking."

"It's not like you forced me." He glanced at her dick, which was still as hard as ever.

"Pretty irresistible, isn't it?" She grabbed her dick just under the flare and groaned happily as a bit more cum dribbled down the back of her hand.

"Here, mistress, you're going to drip everywhere if I don't do something." He leaned in and started licking up the cum that had gotten on her tits, neck, and chin.

"You're such a good girl." She licked the cum off the back of her hand. It tasted a bit like toasted coconut cream with a delicious, salty finish. When his tongue found her, now much bigger, nipples, she moaned.

"Yes, I am." He licked up the cum on her chin and then kissed her muzzle. "This is so surreal. I'm a bit scared." His ears started lengthening and he gasped from his nose pressing inwards while his jaws pressed outwards.

"I know, I'm sorry it's happening this way." She hugged him against her.

He hugged back for a moment, taking deep breaths.

"There, there. Just relax and I'll be here to help you through this." She held him tighter.

Burying his growing muzzle against her neck, he held tightly onto her. She rubbed his back, helping to ease out some tension. His breaths became slower and less anxious.

"I love you. So much." She said, feeling her eyes get wet. This situation was a bit overwhelming now that she wasn't swept up in her instincts.

"I love you too and I..." He paused. "I want to be your girl for real."

"Oh, I've always seen you that way. Since the moment you shared how you really felt inside." 

He let go of her and looked into her eyes. "I know, I'm so happy you could see it even when I couldn't."

"Well, I think seeing yourself that way is about to get a lot easier." She reached between them and lightly touched the growing mounds on his chest.

He moaned and squirmed, his cock pressing into her thigh.

"Yep, you're growing tits, dear." She grinned.

He let go of her. Light, sandy-colored scales were already covering his neck and the lower part of his snout while darker scales, with a bit more orange in them, were spreading to cover the rest of his head, shoulders, and elsewhere.

"Maybe we ssshould hit the ssshowerssss?" His speech was clumsy due to his snout lengthening. As he spoke, his eyes motioned toward their numerous onlookers.

"Good idea." As she got up, she noticed Cash, the Tigress, the redhead, and the deer all taking in the majesty of her massive member. It was so big that she didn't even attempt to hide it, or the pendulous balls that swayed below it. Even though she was quite the spectacle, there was no grace in motions as she stood up. Her thick shark tail was desperately trying to figure out how to help rather than hinder her balance and the scene was downright comedic.

As they worked to put the weights away, Taylor spread his legs, gasping.

"Are you already changing down there?" Her prick throbbed with expectation, getting a mixture of pre and cum on his gym shorts.

"S-something just pressed up inside me from my ballsac." He spoke just barely loud enough for her to hear.

"Oh wow! Let's get you to the showers." She lifted him right off the floor, carrying him the same way she'd carry him over the threshold of a new home.

"NGH!" He squirmed in her arms. The back of his gym shorts had a little, growing tent from his tail.

"Huh, you already smell more like a girl than a guy. You might be changing faster than I did." She used his shoulder to push the swinging door open, her cock and balls flailing due to her staggered steps.

"Mistress, can I really just be a girl now? Like all the time?" He--she said it almost too softly to hear.

"Of course!" She kissed Taylor's scaly forehead. "I'm glad you finally let yourself have this."

"I'm so happy." Taylor smiled shyly.

"To celebrate, how about I christen your new pussy with my cum?" She kissed Taylor's forehead.

Taylor nodded, showing many of her growing shark teeth as she grinned excitedly.

The shower room had standard, mundane white tiles with black grout. Less mundane were the wide, stainless steel shower heads that provided a rain-shower-like spray when someone turned one of the several hotel-style handles. 

Taylor was on shaky legs when Essa set her down and Taylor yelped as her tail tore the seam at the back of  gym shorts. After pulling off Taylor's gym shirt to expose her nice, round tits, Essa quickly knelt down and helped Taylor out of her shoes, shorts and boxers. A floral scent, like a softly-smelling rose mixed with melon hit Essa's senses. Essa leaned in toward Taylor's plumpening ball sac and took in the building feminine scent from between Taylor's legs.

A high-pitched moan escaped Taylor's lips as Essa's snout got right up to her balls. "This is so embarrassing."

"No need to be embarrassed. Good girls need a lot of attention to be happy." Essa nuzzled under Taylor's sac as scales grew across it. Then she used her long tongue to lick across the heated flesh behind it.

"Haaah!" Taylor grabbed Essa's head as she spread her legs.

The delicious mixture of rose and melon flavors Essa was getting from Taylor's snatch, urged her on. She could feel Taylor's passage opening up deeper and deeper with each lick she made into her. Her prick got painfully hard and precum started dripping from the tip. She took Taylor's nice, round ass in her hands and dug her blunt claws into it as she lost herself to eating Taylor out. She'd always dreamed of licking out another woman and it was hotter than she could've ever imagined.

Taylor's voice was getting higher and higher pitched as she moaned from Essa's thorough exploration of her new pussy. Her tail shoved out of her, longer and longer while a sharp, pulsing pleasure enveloped her entire dick. Her ears lengthened along with her snout while her breasts and hips filled out even more. The waves of pleasure from Essa's oral treatment started stealing her breaths. Gasping and moaning, she held firmly onto Essa's scaly head and rocked her hips as her cunt suddenly exploded with pleasure.

"Oh! Oooh! OH! NYAAAH! EEEYYYYAAAHH!" She ground her clit against Essa's snout as that explosion stretched out for ages. It was so different from cumming from her cock that she'd been completely unprepared. The clenching of her inner walls as she milked Essa's tongue accompanied a deluge of warmth and ecstasy that filled her entire body.

While Taylor was cumming, Essa left her tongue in deep while wiggling it slowly to make sure Taylor's release lasted as long as possible. Her reward was getting to drink down lots of Taylor's tasty girl cum. When the orgasm was over, Essa retrieved her tongue and stood up.

"That was incredible, missstressss." Taylor looked up at Essa, her shark snout completing its growth while she was trying to speak.

"Would you believe it was my first time licking a girl out?" She grinned.

"Wait, really?" Taylor's jaw dropped.

"Yeah, and you were delicious." She put her index finger on Taylor's chin and guided her to tilt her snout up. Then she kissed Taylor, sharing the incredible flavor of Taylor's girl juice.

After their snouts parted, Taylor said, "I really am delicious."

"At the end, I couldn't reach my tongue all the way, so I think it's time to make you even more delicious by giving you a cream filling." She motioned for Taylor to turn around. "Lift that thick tail out of the way and let your mistress have her way with you."

"Yes, ma'am." Taylor blushed as she turned around and lifted her tail, feeling very exposed. "Sorry I'm so short compared to you."

Bending her legs to get to the right height, Essa said, "Ehh, it's fine. I haven't done my squats yet today."

"True." Taylor paused. "Sh-should we even be doing this in here?"

"Probably not, but I'm too hard to care." She lined the head of her prick up and grabbed midway down Taylor's tail. "You ready?" 

"Ngh! Yes!" Taylor pressed back against Essa's flare.

Essa pushed her hips forward, spreading Taylor's wonderfully plush pussy lips over her flare. She gasped at the feeling of that hot, wet softness yielding to her turgid flesh. Then, her flare popped inside Taylor and she groaned in delight. Pre streamed from Essa's tip and she nearly came on the spot. She could feel Taylor's passage parting for her while Taylor's moans were getting louder and louder. She growled as she got in half way.

"That's so aaaahhhmazing!" Taylor shivered in delight only to freeze as she looked between her legs. "What the fuck?!"

"Something wrong?" Essa tilted her head.

"Oooh, mmnnnhhh!" Taylor fidgeted. "My dick's splitting down the middle and getting longer. It feels so-OH good."

"Oh, you're getting a pair of shark cocks? Neat!" With her increased height, and how small Taylor was, she just bent down and looked over Taylor's shoulder. Lo and behold, Taylor's prick was swiftly becoming two, beautiful, reddish-orange shark dicks.

She grabbed one in each hand and stroked as they got longer and longer. Taylor's balls expanded right along with them, looking gorgeous. She started fucking her with half her cock while going a little deeper each time. Taylor moaned and writhed, her pricks growing to  a foot long before she screeched and started bucking her hips wildly..

As Taylor spurted cum all over the shower room floor, Essa enjoyed the pulsing of Taylor's depths.Essa gave her little thrusts that made her cry out even louder. The more of her dick she got inside Taylor's snatch, the better, and more satisfying, it felt. 

When Taylor's orgasm ended, she said, "More! I want all of you!"

"Then you shall have every inch!"  Essa's entire shaft had a taper to it, leaving the base thicker than the tip and she was able to thrust almost all the way in to her medial ring.

Taylor let out a sharp moan as she clenched around Essa's shaft, halting Essa's advance.

"Just take a couple deep breaths and relax, dear. No one starts out knowing how to take something this big. And if it hurts too much at any point, we'll stop." Essa put her free hand on Taylor's back to soothe her while she pulled back a bit.

"Okay." Taylor took a couple deep breaths and relaxed.

"That's it, you're doing great, honey." Essa patted Taylor's back. 

The tension inside Taylor's cunny decreased dramatically as she took a couple more breaths.  

"That's a good girl!" Essa smiled.

"Ngh! I like hearing that too much." Taylor looked back at Essa.

"You like it just the right amount in my opinion. Now keep breathing and just enjoy the sensations." She pulled back an inch and then slid forward until her medial ring popped inside. "FUCK! That felt good!" Her dick pulsed as pleasure cascaded down it.

"Give me everything! Please!" Taylor pressed backwards.

"Needy girl!" Essa cheered as she shoved the rest of her shaft in.

"Haaah! Feels so good!" Taylor paused as she looked down at her belly and then put her hand on it. "Oh wow! Essa, feel my belly."

Essa reached around and placed a hand on Taylor's belly. Her eyes widened as she felt her flare under her hand and then felt along her shaft through Taylor's flesh. Her heart started pounding: the way Taylor's small body was stretching to contain her titanic shaft and it made her feel so incredibly sexy.

An instinct to rut consumed her and she thrust most of her shaft in and out. "I'm gonna breed you!"

The swinging door opened and the tigress walked through, the head of her red horsecock still sticking out of the right leg of her gym shorts. Pre fell from the tip as she grinned at the scene in front of her.

"I see a very attractive pussy that could use some attention." The tigress said as she pulled off her gym shirt, exposing two massive tits with red nipples. "May I?"

"Yes, please!" Essa licked her lips as she watched the tigress extract her long, thick horsecock from her gym shorts and panties.

"Thought you might want some help." The tigress walked up behind Essa and leaned down. Then she took a deep sniff of Essa's snatch before licking across it with her rough tongue. "Mmm. A bit like guava, very nice." Then she stood up and put the head of her horsecock right up against Essa's scaly, teardrop-shaped pussy and teased Essa with her thick flare.

"Stop being a tease and give it to me!" Essa thrust backwards, plunging the tigress's flare into her depths. A giddy joy accompanied the pleasure as she thrusted into Taylor and then back toward the tigress: there was nothing quite like being a herm.

"Remember, you asked for this." The tigress shoved forward as Essa pulled out of Taylor a second time. 

"Hnnngggh! FUCK!" The tigress's equine length was so thick that Essa's larger size didn't exactly make things easy, but it did help a lot. It only took about five thrusts to get all sixteen inches of it inside her. And when the medial ring popped in, she nearly came.

"Akiko's the name you should scream when you cum," the tigress said as she worked up to giving Essa nice, hard thrusts.

"Fuck, Akiko, you're getting in so deep!" Essa panted out.

"Rrrrhhh! I'm glad you can take all of me." Akiko grabbed Essa's hips and thrust so hard with her powerful thighs that she drove Essa into Taylor. Essa grabbed Taylor's dicks in her hands, wanting to make her cum both ways.

Just as Essa was getting used to the rhythm of their herm rutting, the chubby redhead and Cash walked in, looking nervous.

"Had a feeling y'all wanted to be herms. Get your mouths on Taylor's dicks now." Essa let go of Taylor's twin lengths. Then she snapped her fingers and gestured for them to move in front of Taylor. "She's about to blow again."

"The moment I saw you sprout that dick, I wanted in." Cash grinned.

"More herms is always good," Akiko said as she resumed stuffing Essa with her impressive horsecock.

As the two wannabe herms got into position, Essa was moaning and gasping. The tops of her feet, backs of her hands, and her entire abdomen were burning with pleasure. She could feel her belly deforming from Akiko's shaft while she made an obvious bulge in Taylor's abdomen every time she hilted herself in her. Then there were the wonderful smacks from all three of their sizable ballsacs as they went at it. Essa knew some of what Taylor was feeling because Akiko was equally as hung as her. Akiko had turned something awesome into something astounding.

Taylor moaned loudly as Cash and the redhead took her dicks into their mouths. Her pussy started twitching around Essa's length and everything felt even better.

"Mistress, I'm gonnAAAH, GONNAAAAH!" Taylor moaned out.

"Then be a good girl and CUM!" Essa drove herself extra hard into Taylor, growling as she started going at a frantic pace.

Essa's cock was so hard it was tingling and had pressure behind it while her Tail-Virus-altered pussy was teetering on the edge of cumming. 

Taylor's snatch started undulating while she spurted cum into the two waiting mouths. 

"Making more herms?. Fuck that's hot!" Akiko roared as she slammed into Essa so hard she made Essa hilt herself in Taylor. Akiko's flare expanded along with her medial ring as her cock lurched. "I'm CUMMING!" Her shaft flooded Essa's cunt with rope after rope of spunk.

"AKI! TAYLOR! HAAAAAHH! GRRAAAAAHH!" Essa's dick pulsed from base to tip, fighting Taylor's gripping flesh. Then Essa felt a shockwave of pleasure travel up her shaft as she let loose a torrent of her thick, pearly jizz. Her medial ring and flare expanded, sealing her seed inside Taylor.

Along with this, Essa's pussy sent waves of pleasure crashing through her. The combined sensations of her cumming while someone was cumming inside her made her screech and writhe between her two lovers. Her thick shark tail bucked between Akiko's heavy tits while she fought with Taylor's tail to keep it from whacking her in the face.

The three herms were panting for breath when their orgasms ended. The soon-to-be herms were gasping and moaning as their chests swelled with tits and their faces pressed out into muzzles.

"Herms are the best." Essa grinned.

"They really are." Akiko nuzzled Essa's tail.

"Fuck, I love being a herm," Taylor panted out.

"Let's make more." A toothy grin graced Essa's muzzle as she thought about having a nice big house party. Or maybe, a pool party: their apartment complex did have a pretty nice pool area...
